Ethylbenzene is an organic compound with the formula C 6 H 5 CH 2 CH 3. It is a highly flammable, colorless liquid with an odor similar to that of gasoline . This monocyclic aromatic hydrocarbon is important in the petrochemical industry as a reaction intermediate in the production of styrene , the precursor to polystyrene , a common plastic ...
The p-xylene is then separated out in a series of distillation, adsorption or crystallization and reaction processes from the m-xylene, o-xylene, and ethylbenzene. Its melting point is the highest among this series of isomers, but simple crystallization does not allow easy purification due to the formation of eutectic mixtures.
At an exposure of 100 ppm, one may experience nausea or a headache. At an exposure between 200 and 500 ppm, symptoms can include feeling "high", dizziness, weakness, irritability, vomiting, and slowed reaction time. [20] [21] The side effects of exposure to low concentrations of xylene (< 200 ppm) are reversible and do not cause permanent ...
If ethylbenzene is included, the mixture is sometimes referred to as BTEX. The BTX aromatics are very important petrochemical materials. Global consumption of benzene, estimated at more than 40,000,000 tons in 2010, showed an unprecedented growth of more than 3,000,000 tons from the level seen in 2009.
ethylbenzene, an industrial solvent used in the production of styrene; toluene and xylene, highly poisonous petrochemical solvents. Toluene is a component of high-octane gasoline; xylene is used in the production of polyester fibers and resins. trichloroethylene, an industrial degreasing solvent; Organophosphate pesticides
Several other identified toxic gases emitted (following the interaction of the chemicals concerned with water and air) include acrolein, acrylonitrile, ethylbenzene, hydrogen chloride, D-limonene, toluene and xylene, which if inhaled, can cause headache, nausea, fainting and breathing difficulty.
Diethylbenzenes arise as side-products of the alkylation of benzene with ethylene, which can be described as two steps. The first step is the industrial route to ethylbenzene, which is produced on a large scale as a precursor to styrene. C 6 H 6 + C 2 H 4 → C 6 H 5 C 2 H 5. The diethylbenzene is an inadvertent side product. C 6 H 5 C 2 H 5 ...
The study is trying to identify the exposure of workers to a variety of chemicals linked to health problems contained in the oil and natural gas released during the accident, including benzene, ethylbenzene, toluene, xylene, and the chemicals contained in dispersants used during the spill. The team will look at long-term problems such as cancer ...
